M92 without parameters

Should now try M92 without parameters in config.h

chris4

Homing failed without M92 parameters on config.h file, have tried to send M92 on G code but nothing happens

chris4

noticed that when I move Z axis +0,5 =2mm, +5 = 20mm, +25 = 100mm up is it correct?

M92 X160.00 Y160.00 Z1600.00 E837.08

Your M92 command in config.g file should looks like this M92 X160.00 Y160.00 Z400.00 E837.08

chris4

Have tried it with M92 X160.00 Y160.00 Z1600.00 E837.08,
but it will be the same

dc42

No, send M92 without parameters from the console. It will report the current M92 settings. Use this to check that the value that you think you have set in config.g is the value being used by the firmware.

It is same, if your Z value is 1600. You should change it to 400.

The answer from the console :
M92
Steps/mm: X: 160.000, Y: 160.000, Z: 1600.000, E: 837.080

And from config.h
M92 X160.00 Y160.00 Z1600 E837.08 ; set steps per mm

Phaedrux

Change your config.g

M92 Z1600 should be M92 Z400

droftarts

@Phaedrux that’s six times now we’ve told him to change Z1600 to Z400!

Phaedrux

@droftarts Ten if you count the times I've shouted it at the screen.

chris4

@droftarts
have tried with the M92 Z400 it too but it will be the same height on the Z axis.
Changing the Z steps/mm from 1600 to 400 cannot fail to reduce the Z height by a factor of 4.

How have you "tried" this? Have you changed your config file? Btw its config.g, not config.h

@chris4 Repeat - Change the M92 in CONFIG.G from 1600 to 400

chris4

@deckingman
As I had written earlier in posts I have tried with the Z400 in config.g
And it became the same height on the Z axis (80mm).
because you said, I have tested again and it became the same height (80 mm)

Phaedrux

Post your entire config.g please.

@chris4 your config.g is correct, with z400 in the M92 command. But have you reset the printer, or power off/power on, or sent M999, or pressed emergency stop in DWC, or sent M98 P”config.g”?

Because the settings in config.g won’t take effect until the machine is rebooted, or the config.g is run again.

I suggested you sent M92 Z400. I didn’t specify how to do this, unfortunately. You can send gcode commands directly in the DWC, in the console window, to see the response. This is also where you can send M92 on its own to see the current setting.

I’m sorry if this is not obvious to someone who is new to Duet, but most of these basic interactions are covered in the documentation.

M92

Yes, have done.
This is from G console :
21:45:11M92
Steps/mm: X: 160.000, Y: 160.000, Z: 400.000, E: 837.080
21:44:47Connection established!
21:44:43Disconnected.
21:44:05M92 Z400.
will try printing again afterwards

droftarts

@chris4 that looks like a correct response. Test how far the z axis moves before printing. Moving Z +10 should move it 10mm, not 40mm. Once print starts, send M92 again, to check it hasn’t changed. I can’t see anywhere in the Gcode you posted that would change, but it’s possible that it may get set somewhere else. Though I think this unlikely.

As I had written earlier in posts I have tried with the Z400 in config.g

I don't want to labour the point but actually in your earlier posts, 4 times you said config.h rather than config.g.

Now that you get the correct response when sending M92, if you still have problems, check to see if you have M92 Z 1600 anywhere else which is overriding the value that you have put in config.g. Places to look would be config_override.g if you use that, or in your slicer start gcode.

chris4

Have done a hard reset on duet2wifi and tried again with the Z400, and now works. 20x20x20
Thanks guys, that you may have an understanding with an old man, but there will certainly be more questions in the future.
Thanks again.

Phaedrux

Glad it finally worked.

The config file is only read at startup. So any changes made to it will require a restart. The Web control will prompt to restart after saving a change.
